South Africa v Australia: fourth Test, day one – as it happened

Close of play: South Africa 313-6

That was a fun and interesting first day, which ends with South Africa slightly ahead. Aiden Markram made a lovely, career-best 152 before the tireless pair of Pat Cummins and Chadd Sayers dragged Australia back into the match after tea. It’s a big first session tomorrow. It’s always a big first session tomorrow. You can join Jonathan Howcroft for that. Thanks for all your interesting emails about that sandpaper business. Bye!
